Note to Readers
There are two sets of document histories in the 810-005 document, and these 
histories are reflected in the header at the top of the page. First, the 
entire document is periodically released as a revision when major changes 
affect a majority of the modules. For example, this module is part of 810-005, 
Revision E. Second, the individual modules also change, starting as an initial 
issue that has no revision letter. When a module is changed, a change letter 
is appended to the module number on the second line of the header and a 
summary of the changes is entered in the module's change log.

This module supersedes module INT-10 in 810-005, Rev. D.

1 Introduction

1.1 Purpose
This modular handbook has been approved by the Deep Space Mission Systems 
(DSMS) Engineering Program Office and is published as a source of interface 
design data for all flight projects using the Deep Space Network (DSN). It 
provides information useful to flight projects contemplating the design of 
hardware and software, with reasonable assurance that the resulting project 
telecommunications interfaces will be compatible with the established or 
planned DSN configurations.

1.2 Scope
The handbook consists of modules that present technical information applicable 
to the current DSN configuration and preliminary information applicable to 
future DSN configurations. These modules will be revised to reflect new 
capabilities and distributed to all users as these capabilities become 
approved by the DSMS Engineering Program Office.

This handbook is primarily concerned with performance parameters of equipment 
that supports the forward and return telecommunications link interfaces 
between spacecraft and the DSN. Other interfaces, such as ground data 
interfaces and administrative interfaces, are covered in a companion handbook, 
the Telecommunications and Mission Operations Directorate (TMOD) Document 810-
007, DSMS Mission Interface Design Handbook.

1.3. Distribution
This handbook is published as an electronic document. However, organizations 
or individuals under contract to, or having received a request for proposal 
from, the National Aeronautics and Space Administration (NASA) or one of its 
centers, may receive loose-leaf bound printed copies upon request to the DSMS 
Engineering Program Office or the editor of this document. Persons receiving 
printed copies will normally be notified of revisions by electronic mail but 
may also request delivery of printed revisions. Persons having no further use 
for printed copies of the document are requested to return them to the editor 
of this document. The purpose of this request is to minimize the possibility 
of documents remaining in circulation if they are not being maintained. 
Requests for mailing address changes should also be submitted to the editor of 
this document.


2 General Information

2.1 Constraints
The disclosure of a capability by this handbook does not ensure that it can be 
made available to all potential DSN users. Specific support commitments must 
be negotiated between individual flight projects and the TMOD Plans and 
Commitments Office. Details about this office, names for personnel to contact, 
and their electronic addresses are available at the following website: 
<http://deepspace.jpl.nasa.gov/advmiss/>. Furthermore, this handbook does not 
relieve projects of the responsibility for obtaining frequency spectrum 
support for their equipment designs. This spectrum support is obtained through 
the JPL Frequency Manager, who is resident in the Plans and Commitments 
Program Office . In seeking viable solutions to telecommunications or data-
processing problems, flight projects are not necessarily constrained by the 
effective design parameters contained in this handbook. However, flight 
project requirements that could require DSN interface design beyond what is 
specified by this handbook are subject to negotiation with the Plans and 
Commitments Program Office. The term user appears throughout this handbook 
whenever a mode of operation or parameter must be selected by a flight 
project. It must be understood that it is only in rare cases that these 
decisions can be made in real time. All DSN activities are planned well in 
advance and conducted by highly skilled persons trained in handling 
contingencies. Changes to planned operations must be made in accordance with 
DSN procedures that are beyond the scope of this document.

2.2 Types of Data
It is the intent of this handbook to provide data verified by measurement and, 
therefore, representing actual performance. Unless clearly marked to the 
contrary, data in this handbook should be assumed to comply with this intent. 
Sometimes it is necessary to include DSN design performance data that have not 
been verified by measurement. These data will be clearly identified in the 
associated text or by appropriate marking. As hardware and software are tested 
and evaluated under operational conditions throughout the DSN, performance 
parameters will be upgraded to represent actual performance and published in 
the next revision of the appropriate module.

2.3 Proposed Capabilities
Whenever sufficient information is known about a capability being implemented 
in the DSN and having adequate maturity to be considered for spacecraft 
mission and equipment design, this information will be included in the 
appropriate modules under the heading of Proposed Capabilities. 
Telecommunications engineers are advised that anything discussed under this 
heading cannot be committed to except by negotiation with the TMOD Plans and 
Commitments Program Office.

2.4 Document Layout
The modules in this revision of 810-005 have been divided into major sections 
that can be identified by their module numbers and the color of the tabs in 
the printed version or the index to the on-line version. This module is part 
of an introductory section that may be expanded in the future to include 
tutorial or summary information. Modules in this section have yellow tabs and 
numbers starting with 0. The next section, Space Link Interfaces, contains 
modules that provide information to those concerned with antenna selection and 
propagation effects. Modules in this section have blue tabs and numbers 
starting with 1. The third section, Station Data Processing, contains modules 
that provide capabilities and performance of equipment installed in the Signal 
Processing Center (SPC) portion of each DSN location. This information will be 
of interest both to telecommunications engineers and spacecraft mission 
designers. Modules in this section have green tabs and numbers starting with 
2. The fourth section in this revision, Ground Station Properties, contains 
modules that provide information about the underlying technologies relating to 
many of the Space Link Interfaces and Station Data Processing modules. These 
modules have been grouped to consolidate this information in one place. 
Modules in this section have brown tabs and numbers starting with 3.

2.5 Module Revision and Control
The modules contained in this handbook are approved for publication under the 
authority of the cover page signatories. Revisions are indicated by a revision 
letter following the module designator. A summary of the changes and additions 
to the on-line version of 810-005 can be accessed on the home page of the 
document, located at the website listed on the cover and title page of this 
document. Currency of modules in printed copies can be verified against the 
information in the Table of Contents supplied with each revision or by 
comparison with the online version. Minor corrections or changes to printed 
copies may be issued in the form of module change pages that will be 
appropriately marked and recorded in a Change Log near the front of the 
module. Persons requesting additions of modules to the handbook should direct 
their request to the DSMS Engineering Program Office. Persons requesting 
changes, corrections, or additions to existing modules should direct their 
comments to either of the cover page signatories or to their functional titles 
at the DSMS Engineering Program Office. All modules are subject to the review 
and approval process of TMOD Standard Practice, DSMS Documentation Structure, 
Standards, and Definitions; TMOD Document 810-001.

2.6 Abbreviations
Abbreviations are normally defined after their first textual usage and are 
compiled in module 901, Handbook Glossary. It should be recognized, however, 
that certain common abbreviations or acronyms used in this handbook may not 
defined. External users may refer to any of several compilations of electronic 
terms for omitted definitions. Users with access to the JPL Intranet can find 
additional abbreviations in DSMS System Engineering Standard; DSMS 
Abbreviations and Acronyms, TMOD Document 820-062.
